" The earth was quiet around him, but alive. He felt it through the soles of his feet when he walked. The vibrancy of the forest streamed into him, strengthening him. But there was less of it than there should be. The world had changed, and was still changing. It was being tamed, losing its feral wildness and strength. Alongside it, his power was dimming as well. He was still unmatched, but there were blind spots in his communion with the earth, and those blind spots were growing, shutting him off bit by bit, reducing him. The realms of men were expanding, scouring the earth, parsing it into meaningless plots and fields, breaking up the magic polarities of the wilderness... That which made him so powerful, his connection to the earth, was also becoming his only weakness. In a cold rage, he walked. As he passed, the trees spoke to him, but even the woodsy voices of the naiads and the dryads was dimming. Their echo was confused and broken, divided. "
